Definitions

  • This invention relates to a halogen-free resin composition containing metal hydroxide, to a method of making the resin composition and to electrical wire having this resin composition as a covering on an electrical conductor core.
  • Such an electrical wire is useful for example in a motor vehicle.
  • Polyvinyl chloride has been much used as the covering material of electrical wire for an automobile, because it is superior in properties such as mechanical strength, extrusion processability, flexibility and colouring property.
  • halogen-free resin material has come to be used for the production of automobile parts including the covering of electrical wires in an automobile in place of polyvinyl chloride, because polyvinyl chloride discharges a harmful halogen gas on combustion.
  • a halogen-free resin composition in which a metal hydroxide is blended with a polyolefin-base polymer as a flame-retardant is known as a wear resistant resin composition having the merit of no generation of a poisonous gas such as a halogen gas on combustion (see JP-A-7-176219 , JP-A-7-78518 and the like).
  • a flame-retarding resin composition has a self-extinction property, a large quantity of a metal hydroxide is required to be added, but this causes problems that mechanical strength such as the wear resistance, tensile strength and the like of the composition are much reduced.
  • JP-A-6-290638 discloses resin compositions containing metal hydroxide for electrical wire insulation, in which the resin composition is based on polypropylene (>80%). Additional components are polyethylene modified with acid anhydride and styrene copolymer.
  • US-A-5561185 describes resin composition for electrical wires containing metal hydroxide, in which the resin components are (a) 40 - 88.5% by weight of propylene which is 50% by weight or more of a ethylene/propylene random copolymer, (b) 1.5 to 30% by weight of a polyethylene modified with carboxylic acid derivative, e.g. maleic anhydride and (c) 10 to 48% by weight of an ethylene-series copolymer, typically ethylene/vinyl acetate copolymer.
  • the resin components are (a) 40 - 88.5% by weight of propylene which is 50% by weight or more of a ethylene/propylene random copolymer, (b) 1.5 to 30% by weight of a polyethylene modified with carboxylic acid derivative, e.g. maleic anhydride and (c) 10 to 48% by weight of an ethylene-series copolymer, typically ethylene/vinyl acetate copolymer.
  • US-A-5180889 also describes a resin composition containing metal hydroxide as a covering of conductors in a crush resistant cable assembly.
  • the resin components are (a) a low density copolymer of ethylene and alphaolefin, (b) an elastomeric styrene-ethylene-butylene-styrene tri-block copolymer, preferably modified with maleic anhydride and (c) optionally an impact propylene and copolymer or polypropylene.
  • Component (a) in the examples is 50% by weight or more of the total resin components.
  • EP-A-273516 proposes flame retardant insulation compositions comprising a functionalized selectively hydrogenated monoalkenyl arene-conjugated diene block copolymer (e.g. styrene-ethylene/butylene-styrene block copolymer modified with maleic anhydride), polypropylene, plasticizer and hydrated inorganic filler (e.g. aluminium hydroxide).
  • a functionalized selectively hydrogenated monoalkenyl arene-conjugated diene block copolymer e.g. styrene-ethylene/butylene-styrene block copolymer modified with maleic anhydride
  • polypropylene e.g. styrene-ethylene/butylene-styrene block copolymer modified with maleic anhydride
  • plasticizer e.g. aluminium hydroxide
  • hydrated inorganic filler e.g. aluminium hydroxide
  • the object of the present invention is to provide a halogen-free olefin-based resin composition
  • a halogen-free olefin-based resin composition comprising a mixture of selected components providing a good balance of properties, for example wear resistance, flame resistance, tensile property, flexibility and the like which are required for the covering material of an electrical wire, e.g. for an automobile.
  • the present invention provides an olefin-based resin composition containing the following resin components:-
  • the invention also consists in an electrical wire having this composition as a covering on a conductor.
  • composition of the present invention are selected to provide in combination the desired properties and are illustrated as follows.
  • the propylene polymer (a) having an MFR of 0.1 - 5 is a propylene homopolymer or a propylene-ethylene copolymer of block or random type whose main monomer component (more than 50% by weight) is propylene.
  • Examples of such a propylene polymer having an MFR of 0.1 - 5 g/10 min. are RB610A, RB410, RB110 and the like which are commercially available from TOKUYAMA Co., Ltd.
  • MFR is measured in accordance with JIS K6921-2.
  • the unit of MFR is g/10min.
  • MFR is indicative of molecular length.
  • the selection of a value of 0.1 - 5 g/10 min. achieves good cold weather performance, in particular avoidance of cracking.
  • Component (b) is a polypropylene modified with 0.1 - 10% by weight of a carboxylic acid anhydride, typically unsaturated acid anhydride e.g. maleic anhydride.
  • the polypropylene (b) preferably has a Shore D hardness of 50 or more.
  • the amount of component (b) in the total of 100 parts by weight of the polymers (a), (b) and (c) is 1 - 20 parts by weight, and preferably 5 - 20 parts by weight. When this proportion exceeds 20 parts by weight, flexibility is reduced and processability becomes poor. On the other hand, when the proportion of component (b) is less than one part by weight, the wear resistance is poor.
  • the polypropylene component (b) gives the composition heat resistance, both during extrusion and if over-heating occurs in use, e.g. in an automobile.
  • the styrene-based polymeric elastomer, component (c), is a styrene-based elastomer modified with 0.1 - 10% by weight of a carboxylic acid anhydride, typically unsaturated acid anhydride, for example, maleic acid anhydride.
  • the styrene-based elastomer is preferably a polymer obtained by block-copolymerising styrene with butadiene, and saturating double bonds of the resulting block-copolymer by hydrogenation (known as SEBS).
  • SEBS block-copolymerising styrene with butadiene
  • the ratio of the styrene/butadiene is in the range 3/7 to 2/8 by weight.
  • styrene-based elastomer obtained by block polymerising styrene and isoprene and hydrogenating the double bonds of the block copolymer (this product can be regarded as polystyrene-poly(ethylene-propylene)-polystyrene, and is known as SEPS).
  • the amount of component (c), in the total amount of 100 parts by weight of the polymers (a), (b) and (c) in the composition is 5 - 60 parts by weight, and preferably 5 - 50 parts by weight.
  • this proportion of component (c) exceeds 60 parts by weight, wear resistance is poor.
  • the proportion of component (c) is less than 5 parts by weight, flexibility is reduced and processability becomes poor.
  • the metal hydroxide particles are surface-treated with a coupling agent, particularly a silane coupling agent (for example, an aminosilane coupling agent, a vinylsilane coupling agent, an epoxysilane coupling agent, etc.) and optionally a surface-treating agent such as a higher aliphatic acid (for example, stearic acid, oleic acid, etc.) or the like.
  • a silane coupling agent for example, an aminosilane coupling agent, a vinylsilane coupling agent, an epoxysilane coupling agent, etc.
  • a surface-treating agent such as a higher aliphatic acid (for example, stearic acid, oleic acid, etc.) or the like.
  • the silane coupling agent typically contains Si-O linkages which bond to the hydroxide.
  • Magnesium hydroxide surface-treated with an aminosilane coupling agent is preferable in particular.
  • the amount of the metal hydroxide based on the total amount (100 parts by weight) of the polymers (a), (b) and (c) in the composition is in the range 30 - 200 parts by weight, preferably 50 - 150 parts by weight and more preferably 70 - 100 parts by weight.
  • the amount of the metal hydroxide is too large, the elongation of the composition is reduced and the wear resistance, the flexibility and the processability are poor.
  • the amount of the metal hydroxide is too small, the flame resistance of the composition is reduced.
  • All of the components (a), (b) and (c) are selected to be halogen-free. Synthetic resin components other than components (a), (b) and (c) are substantially absent. Components (a) and (b) are different.
  • Compounding agents usually included in an olefin-based resin composition such as for example an oxidation inhibitor, a copper inhibitor, a lubricant and the like may be present in the olefin-based resin composition of the present invention provided that their amount does not excessively deteriorate the above-mentioned properties.
  • the olefin-based resin composition of the present invention can be prepared by mixing and kneading the respective components according to conventional methods.
  • Covering an electrical wire core, particularly to make an electrical wire for an automobile, by the resin composition of the present invention may be performed by a conventional method.
  • the olefin-based resin composition of the present invention when used as the covering material of an electrical wire, e.g. for an automobile, can provide excellent properties such as wear resistance, flame resistance, tensile properties, flexibility and the like, as are required.
  • the coupling agent bonds the metal hydroxide with the acid anhydride.
  • the coupling agent has a functional group reacting with the inorganic hydroxide and a functional group reacting with the organic anhydride.
  • the epoxysilane and vinylsilane coupling agents have affinity to the hydroxide and the anhydride. Accordingly, the mechanical strength, particularly the wear resistance, can be remarkably improved without damaging the flexibility of the resin composition.
  • the reaction with the polyolefin and the styrene-based elastomer modified with an acid anhydride advantageously suppresses the hydrophilic property of the amino group.
  • Tables 1 and 2 The components shown in Tables 1 and 2 are mixed at the amounts shown (parts by weight), and kneaded at 250°C by a twin-screw extruder. Each composition obtained was extrusion-molded at a covering thickness of 0.3mm around a conductor of 0.5mm 2 cross-section (twisted wire consisting of 7 soft copper wires each of diameter 0.32mm). A die having a diameter of 1.6mm and a nipple having a diameter of 1.0mm were used for extrusion molding. The extrusion temperature was 240 - 260°C for die and 230 - 250°C for cylinders, and the extrusion molding was carried out at a linear velocity of 100m/min.
  • antioxidant a hindered phenol-based antioxidant (trade mark "TOMINOX TT” manufactured by Yoshitomi Fine Chemicals Ltd.) was used.

  • the flexibility was evaluated by touch when the electrical wire was folded.
  • the processability was evaluated by the presence of whisker formation at peeling at the terminal of the electrical wire.
  • Example 1 and Comparative Example 5 show that, when the amount of the styrene-based elastomer modified with an acid anhydride deviates from the range of the present invention, the wear resistance and flexibility of the resin composition are incompatible.
  • Example 2 shows that, when the styrene-based elastomer not modified with an acid anhydride is used, the wear resistance of the resin composition is high, but the flexibility is poor.
  • the composition obtained was extrusion-molded at a covering thickness of 0.2mm around a conductor which is the same as in Examples 1 and 2.
  • a die having a diameter of 1.3mm and a nipple of diameter 0.88mm were used for extrusion molding.
  • the extrusion temperature was 240 - 260°C for the die and 230 - 250°C for cylinders, and the extrusion molding was carried out at a linear velocity of 100m/min.
